Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations HBG or BG identification

Hi all, I am working toward understanding all the pond management stuff as I go. About 5 years ago my pond was stocked with what I thought I remembered being HBG. I struggle understanding the differences from the BG and HBG. Which are these? I will also trap some baby as well. Based on what I see as a spawn I am wondering if these are indeed BG.
